I have a question here.

Why is the Unreal Engine the most used engine in the videogame business. Why does nobody except of Crytek use the Cryengine or the Red Engine?

Is the UE3 really the best engine in the business? I have just read that Dead Space 3 will use the Frostbyte 2, why shouldnt the new Dragon Age use the same one?

My guess is that Unreal is pretty cheap, easy to use and can be used for a wide range of game genres. Frostbite 2 is a new engine, developed by EA/DICE so it'll only be used in EA games, which started with Battlefield 3. Cryengine 3 is being used in quite a few non-crytek developed games.

Expect EA to start using frostbyte where ever possible for there own games, so they dont have to pay Unreal Engine license fees.

Unreal Engine has been here from the start of the generation thats why most use it, why switch to cryteks engine when youve already paid for Unreals, Its expensive to switch, not just in money but also time to get everyone use to the new engine.

What other games use the Cryengine?

Class3, enemy front, Sniper: Ghost warrior 2, mech warrior online and ASTA are all non-crytek games using Cryengine 3, among others.

Cheap, proven, easy to develop (and with that many layed off developers have already worked with that, so time saving is also a factor).

As far as I know the UE3 costs $1m to license. Far cheaper than making your own competing engine.
CryEngine 3 is $1.2m.

CryEngine 3 is used by quite a few third party games: http://en.wikipedia.org/wiki/CryEngine#CryENGINE_3

good positioning basically, Epic were the first to really create a engine with the intention to licence it to third parties. iD Tech was licensed by a lot of games but as Carmack has said he was never really interested in it so he basically just gave devs the source and said have fun, Epic gave devs support and documented their engine.

Also Epic put a lot of effort into getting the engine in devs hands, providing it for free for teaching institutions, and later providing the free UDK for indie devs plus their Make Something Unreal competition. This all basically means that most devs working in the industry has used UE at some point so it is easier to get new stuff up to speed with the tools.

It also helps that UE is a very mature proven engine with great tools and is highly scalable to support a wide range of hardware with a lot of 3rd party add-ons and asset libraries already in place.

Tho Gamebryo is going to be the go to engine from now on

Why do you think that? Or is it sarcasm?

Simple: Everyone knows how to use it by now, it's "cheaper, Epic actually supports it 100% and it has a enermous amount of documentation.

CryEngine 3's available documentation is piss poor in comparison, is more expensive and less friendly to access to (I'm not sure if the devs that license it have the same issue, but the free sdk version has a bloody drm system where you have to be online and sign it to use it -.-)

The only thing CE3 really excells in right now is lighting and terrain system, which is set to change with Unreal Engine 4.
